Qnnrnnx CAMERA. I

To allwham it may concern." .Be it known that I, EBENEZER Goonn,' M. A.,a subject of the Kin of Great Britain, residing at. 6 Green 5Lincolnshire, England, have invented a new v and useful Improved ReflexCamera, of

p which the following is a specification.

ill, Grantham,

My invention relates'to'reflex cameras of the kind in which two mirrorsare used be tween the lens and focusing screen. The object of myinvention is to so at 'range the mirrors that the shutter'is se'pa--rate from and forms no part of them, and so that the camera maybe ofcomparatively small size and easily portable. 1

i by reference to the accompanying drawings,

having the body made in two parts, and Fig.

Referrin trated in Fig. 1, which, as stated above, illustrates acameraof the box form,"a isthe Y body, 2) thelens and o and dthe twomirrors. The mirror 0 receives the image from of thecamera adjacent tothe lens and at such an angle that it will divert the image to thesecond mirror at which is in a plane 3P1 proximately parallelto that ofthe mirror 0,. the rays being reflected from the mirror d'. and directedto the focusing screen 6' whichis in an approximatelyvertical position.The I y shown 1n broken lines, when not required for use. In this formof the invention the back 10o. m, this base board being-designed to.holdv said screen is protected by a hood 7 in the usual manner and isarranged in an approximately vertical plane so thatjthe operator in anapproximately horizontal direction.

The mirror 0 is pivoted at 9 so that it can be moved out of the range oftherays from:

the lens I) at the time of exposure, as shown sprin tions purpose ofviewing by any suitable means,

My imam Wmbe y matador the lens I; and is located in the front portionviews the image which is reflected'thereon in broken lines in Fig. 1..The said mirror."

is'preferably normally held in the position shown-in the broken lines,that is to say, out of the'path of the rays from the lens I) loyal suchas h and is moved into the posiown in full linesin the figure for the'Specification of Letters meat. j Patented Mar. 28, 1916.

ately before the shutter is operated. a

In "the construction shown in Fig. 1, the

mirror d is fixed to the front or lens board of the camera body a, andthe focusing screen e 1s also fixed in position relativelyl to the saidbody. In the construction illustrated 1n Figs; 2 and 3, however, themirror d 1s hmged at i to-the 'camera front or lens {board and thefocusing screen a is hinged at i to the frame carrying the said mirror61'.

Withthis construction the ,said focusing camera is not required for use.f

connectedto the said front board that it may to in the foregoingdescription have'the back "screen can be folded againstthe mirror d' andthe latterturned downward into the position" shown in broken lines whenthe In theform of my invention illustrated in Fig. 1, the lens I) isfixed to the front board I of the body a but the said lens may be'so:

"so that when not required for use it may be I I turned and pushedwithin the body a and beneath the mirror 0' when the latter is 'f raisedas shown in broken lines in Fig. 2.

hinged struts n for retaining it in place when the track is is extended.

When the lens I) is not provided with a "focusing mount-and it isdesired that focusing may be effected 'withthe camera, the

screen e may be, attached to the back part and such a construction isillustrated in Fig. 4, in which the said back part la is attached A bymeans of links Z to the rear of the bodyv The base boardis furnishedwith k holding the shutter and plate holder so as to be movable with thesaid back part.

Such a construction is illustrated in Fig. 5 in which the movement ofthe back part relatively to the body for focusing purposes is elfectedby means of the rack o and pinion 79.

It will be understood that any ordinary suitable means may be made useof for rendering the inside of the camera light-tight when the mirror 0is up for exposure, and also to effectually shut out light betweenhinged or moving parts.

\ Claims.

1. In a reflex camera of the kind referred to, the combination of amirror adjacent to the lens, means for moving said mirror out of thepath of the rays passing through the lens, a second mirror receiving therays from the first mirror and a viewing screen for receiving the" raysfrom the second mirror.

2. In a reflex camera of the kind referred to, the combination of amirror adjacent to the lens and pivoted so that it can be movedout ofthe path of the rays passing through the latter, and-a second mirrorreceiving the rays from the first mirror and a viewing screen forreceiving the rays from the latter, substantially as hereinbeforedescribed.

3. In a reflex camera of the kindreferred to, the combination of amirror adjacent to the lens, means for moving said mirror out of thepath of the rays passing through the lens, a second mirror fixed to thecamera front or lens board and a viewing screen for receiving the raysfrom the second mirror.

4. A reflex camera comprising a casing formed of-a front and rear partmovably connected together, said front part being provided with a lens,a mirror adjacent to the lens and receiving the rays therefrom, meansfor moving said mirror out of the path'of the rays passing through saidlens, a second mirror receiving the rays from the first mirror, and aviewing screen for receiving the rays from the said mirror, and

the rear part of said casing being adapted to carry the shutter andplate holder.

5. A reflex camera comprising a casing formed of a front and rear partpivotally connected together, said front part being providedwith a lens,a mirror adjacent to the lens and receiving the rays therefrom,

means for moving said. mirror out of the path of the rays passingthrough said lens, a second mirror receiving the rays from the firstmirror, and a viewing screen for receiving the rays from the saidmirror, and the rear part of said casing being adapted to carry theshutter and plate holder.
